* lisp/emacs-lisp/package.el: Some speed optimizations on menu refresh

(package-menu--print-info): Obsolete.
(package-menu--print-info-simple): New function.
(package-menu--refresh): Use it, simplify code, and improve
performance.

* lisp/emacs-lisp/tabulated-list.el (tabulated-list-print-entry):
Tiny performance improvement.
